[PATCH v3 4/4] win32u: Forward to Rectangle() if the ellipse width or height is zero.

[Elizabeth Figura]

From: Elizabeth Figura

Before 5924ab4c5155d97f4b23a33e97258c1ec382ea02 we would forward to Rectangle()
if the width or height was <= 2. This is incorrect for scaling transformations,
but forwarding when the dimensions are zero is still correct, and avoids errors.
